Another Cause of DKA in T2DM in COVID-19 Pandemic

Background: 47-year Emirati female, has history of T2DM since age of 39. Her overall diabetes poorly controlled with HbA1C of 8.6% (69 mmol/mol IFCC) on Empagliflozin 10 mg OD over the last 2 years well tolerated. NO micro- or macrovascular complications of her diabetes. No other significant medical history apart from hypertension she is taking Amlodipine 10 mg OD for it with good control. She has presented twice to the hospital 24 hours apart. 1st Visit to ER in our Hospital with fever epigastric pain discharged on Ciprofloxacin suspected gastroenteritis with PPI and sent home. Approximately, 24 hours later she presented again with same symptoms namely fever and epigastric pain but this time associated with diarrhea and nausea for last 20 hours. There was no shortness of Breath or cough. This time she has been admitted to isolating room giving suspicion of COVID-19. Vital signs as following: Temp 38.5 HR 105, BP 135/65 mmHg O2 Sats 96%. on RA. On examination, she was conscious, oriented to time place person. No signs of dehydration. abdomen soft non tender, Chest good air entry no added sound. Hear S1-S2 no murmurs. HRCT has been done at ER. HRCT shows wide spread area of multifocal ground glass opacification are seen in both lungs most of them shows peripheral sub-pleural distribution Around small size consolidation are seen within the ground glass opacification, CT findings are in favour of possibility of COVID-19. Result(s): Blood test as following On admission, FBC was normal, with Hb 13.2, WBC 8.0, Plt 388 cellX 10/ul, U/Es: S.NA 132, s.K 4.2 mmo/l, s. Creatinine normal (58 umol/L -NR 49-90 umol/L) LFTs, Amylase and lipase normal, LDH mild elevation 304 U/L (NR 81-234), Very low Phosphate 03 mmol/L (NR 0.87-1.45), D-Dimer 0.6 mg/L (NR 0.0- 0.5), Corrected Calcium normal, S. Ferritin was 242 ug/L (NR 8.00- 388.00 ug/L), Urinalysis Protein =1 and 4+ ketones, CRP was normal 1 mg/dl ( increased to 214 mg/ l 3rd day) before it goes done 41 mg/L on 7th day of admission. Giving the pandemic of COVID 19 and according to MOHAP Criteria for presenting symptoms. This lady underwent HRCT and COVID19 test by Nasal Swab. Meanwhile, Her Venous Blood gas shows sever metabolic acidosis pH 7.107, PCO2 12.90, PCO2 69.10 On RA, BC 8.9, BE -25.5. Blood sugar 13.2 mmol/L with Urinary Ketones of 4+. Patient has put on DKA Protocol according to our Hospital DKA protocol in addition Stopped her SGLT2 and start on Lantus as a basal. She has put on Scale C (which is the higher scale with infusion about 10 units per hour, for about 96 hours (i.e. 4 days till the blood sugar back to normal for Ketones to disappear, her acidosis didn't improve 1st 24 hours till we give her 1.26% of 500 ml of Sodium Bicarbonate over 6 hours. COVID 19 Test back after 72 hours with positive results. Once out of DKA Diabetes team has stopped her Lantus a stared-on Humalog mix 50% 25 unit TDS. Meanwhile, she has received the following medications waiting for COVID 19 test. Treated with Favipiravir 1600 mg BD for 1 day and 600 mg BD, Start Tazocin 4.5 (stopped after 3 days) Metronidazole, and with prophylactic dose of Clexane. The Hydroxychloroquine hasn't started as Prolong QTC has been notice). Discussion(s): This patient presentation with DKA is another example how COVID- 19 could be a reason for DKA, though SGLT2 could be another cause of her presentation, however the huge insulin requirement and unusual prolong DKA status even with sever acidosis is making COVID-19 more likely causing her presentation It. Conclusion(s): We report this case to highlight the fact DKA - and in fact sever resistant DKA need prolong treatment can happen to Patient with T2DM and COVID 19 positive, and special attention to be paid (with early referral to the diabetes team) if the patient already on SGLT2. And we recommend that to have low threshold to start investigation and treatment as early as possible, regardless the type of Diabetes these patient might have.

Maternal fructose boosts the effects of a Western-type diet increasing SARS-COV-2 cell entry factors in male offspring.

Fructose-rich beverages and foods consumption correlates with the epidemic rise in cardiovascular disease, diabetes and obesity. Severity of COVID-19 has been related to these metabolic diseases. Fructose-rich foods could place people at an increased risk for severe COVID-19. We investigated whether maternal fructose intake in offspring affects hepatic and ileal gene expression of proteins that permit SARS-CoV2 entry to the cell. Carbohydrates were supplied to pregnant rats in drinking water. Adult and young male descendants subjected to water, liquid fructose alone or as a part of a Western diet, were studied. Maternal fructose reduced hepatic SARS-CoV2 entry factors expression in older offspring. On the contrary, maternal fructose boosted the Western diet-induced increase in viral entry factors expression in ileum of young descendants. Maternal fructose intake produced a fetal programming that increases hepatic viral protection and, in contrast, exacerbates fructose plus cholesterol-induced diminution in SARS-CoV2 protection in small intestine of progeny.

Diabetic women: Inpatient mortality risk before SARS-CoV-2.

Background: Type 2 diabetes mellitus is a major driver of mortality worldwide. To assess the risk factors associated with diabetes that increase in-hospital mortality. Methods: A retrospective cohort study was conducted using the National Hospital Morbidity with a sample of 3904 diabetic women admitted (2018-2019) in public hospitals, in Portugal. The type of comorbidities and the severity of the main disease - type 2 diabetes mellitus - was assessed based on the International Classification of Diseases (ICD-9) and Disease Staging. Cox proportional hazard was used to assess mortality during hospitalization. Mortality rates and mortality risk were the main outcome measures. Results: In a total of 3904 diabetic women three hundred and eighty-nine (10.0%) died during hospitalization. Comorbidities bacterial pneumonia and coronary artery disease contributed 73% [Hazard ratio (HR) 1.73, 95% CI 1.32-2.27] and 37% [HR 1.37, 95% CI 1.03-1.81] respectively, to the risk of mortality, as did age over 65 years and severity 3 of the main disease. Conclusions: Women with advanced type 2 diabetes mellitus, advanced age, and with comorbidities such as pneumonia and coronary artery disease admitted urgently have a higher risk of mortality during hospitalization.

Enhanced endocytosis elevated virulence and severity of SARS-CoV-2 due to hyperglycemia in type 2 diabetic patients.

Diabetes mellitus is a metabolic disease that causes hyperglycemia. In COVID-19 patients the severity of the disease depends on myriad factors but diabetes mellitus is the most important comorbidity. The current review was conducted to investigate the virulence of SARS-CoV-2 and disease severity of COVID-19 in type 2 diabetes mellitus patients and relevant treatment. The literature published in PubMed, Scopus, Web of Science, and Google Scholar was reviewed up to September 2021. The keywords including SARS-CoV-2, type 2 diabetes mellitus in COVID-19, hyperglycemia in COVID-19, opportunistic infections in type 2 diabetes mellitus and COVID-19 were used in different combinations. Hyperglycemic individuals over-express ACE-2 receptors in the lungs thus increasing the SARS-CoV-2 susceptibility and replication. Although dipeptidyl peptidase-4 plays an important role in glucose homeostasis, additionally it also stimulates the production of proinflammatory cytokines such as IL-6 and TNF-α creating a cytokine storm. Cytokine storm might be responsible for respiratory insufficiency in severe COVID-19 patients. Type 2 diabetes mellitus is associated with immunosuppression and the patients are prone to get many opportunistic infections. Type 2 diabetes mellitus patients with severe COVID-19 have lymphopenia. Moreover, in type 2 diabetes mellitus patients the neutrophils exhibit decreased chemotaxis, hydrogen peroxide production, and phagocytosis. Reduction in lymphocyte count and defective neutrophil capacity renders them with COVID-19 susceptible to opportunistic bacterial and fungal infections increasing the mortality rate. The opportunistic bacterial infections in COVID-19 patients were due to Staphylococcus aureus, Streptococcus pneumonia, and coagulase-negative Staphylococci, E. coli, Pseudomonas aeruginosa, and Klebsiella sp. In COVID-19 patients with type 2 diabetes mellitus, mucormycosis was found to be the most common fungal infection with a higher predilection to males. Hyperglycemia in COVID-19 patients with type 2 diabetes mellitus enhances the SARS-CoV-2 replication with an adverse outcome. A strong correlation exists between the poor prognosis of COVID-19 and type 2 diabetes mellitus. Proper glycemic control in COVID-19 patients with diabetes mellitus might lessen the severity of the disease.

Outpatient and inpatient anticoagulation therapy and the risk for hospital admission and death among COVID-19 patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with a hypercoagulable state. Limited data exist informing the relationship between anticoagulation therapy and risk for COVID-19 related hospitalization and mortality. METHODS: We evaluated all patients over the age of 18 diagnosed with COVID-19 in a prospective cohort study from March 4th to August 27th, 2020 among 12 hospitals and 60 clinics of M Health Fairview system (USA). We investigated the relationship between (1) 90-day anticoagulation therapy among outpatients before COVID-19 diagnosis and the risk for hospitalization and mortality and (2) Inpatient anticoagulation therapy and mortality risk. FINDINGS: Of 6195 patients, 598 were immediately hospitalized and 5597 were treated as outpatients. The overall case-fatality rate was 2•8% (n = 175 deaths). Among the patients who were hospitalized, the inpatient mortality was 13%. Among the 5597 COVID-19 patients initially treated as outpatients, 160 (2.9%) were on anticoagulation and 331 were eventually hospitalized (5.9%). In a multivariable analysis, outpatient anticoagulation use was associated with a 43% reduction in risk for hospital admission, HR (95% CI = 0.57, 0.38-0.86), p = 0.007, but was not associated with mortality, HR (95% CI=0.88, 0.50 - 1.52), p = 0.64. Inpatients who were not on anticoagulation (before or after hospitalization) had an increased risk for mortality, HR (95% CI = 2.26, 1.17-4.37), p = 0.015. INTERPRETATION: Outpatients with COVID-19 who were on outpatient anticoagulation at the time of diagnosis experienced a 43% reduced risk of hospitalization. Failure to initiate anticoagulation upon hospitalization or maintaining outpatient anticoagulation in hospitalized COVID-19 patients was associated with increased mortality risk. FUNDING: No funding was obtained for this study.

COVID-19 Presenting With Diabetic Ketoacidosis: A Case Series.

OBJECTIVE: Diabetes mellitus has been recognized as one of the comorbidities that predict the severity of illness in patients infected with COVID-19. The characteristics of patients presenting with diabetic ketoacidosis (DKA) and COVID-19 infection have not been described. METHODS: We describe 5 patients with DKA and concomitant COVID-19 admitted to the intensive care unit of an academic medical center. Three patients had type 1 diabetes mellitus, and 2 patients had type 2 diabetes mellitus. RESULTS: While DKA with an infectious etiology is a common presentation, we observed that the patients with DKA precipitated by COVID-19 presented with atypical symptoms. COVID-19 infection was revealed during search for an etiology of DKA. CONCLUSION: It is prudent to have a low threshold to screen for COVID-19 infection in patients with DKA.

Left ventricular global longitudinal strain in identifying subclinical myocardial dysfunction among patients hospitalized with COVID-19.

BACKGROUND: The incidence of acute cardiac injury in COVID-19 patients is very often subclinical and can be detected by cardiac magnetic resonance imaging. The aim of this study was to assess if subclinical myocardial dysfunction could be identified using left ventricular global longitudinal strain (LV-GLS) in patients hospitalized with COVID-19. METHODS: We performed a search of COVID-19 patients admitted to our institution from January 1st, 2020 to June 8th, 2020, which revealed 589 patients (mean age = 66 ± 18, male = 56%). All available 60 transthoracic echocardiograms (TTE) were reviewed and off-line assessment of LV-GLS was performed in 40 studies that had sufficient quality images and the views required to calculate LV-GLS. We also analyzed electrocardiograms and laboratory findings including inflammatory markers, Troponin-I, and B-type natriuretic peptide (BNP). RESULTS: Of 589 patients admitted with COVID-19 during our study period, 60 (10.1%) underwent TTE during hospitalization. Findings consistent with overt myocardial involvement included reduced ejection fraction (23%), wall motion abnormalities (22%), low stroke volume (82%) and increased LV wall thickness (45%). LV-GLS analysis was available for 40 patients and was abnormal in 32 patients (80%). All patients with LV dysfunction had elevated cardiac enzymes and positive inflammatory biomarkers. CONCLUSIONS: Subclinical myocardial dysfunction as measured via reduced LV-GLS is frequent, occurring in 80% of patients hospitalized with COVID-19, while prevalent LV function parameters such as reduced EF and wall motion abnormalities were less frequent findings. The mechanism of cardiac injury in COVID-19 infection is the subject of ongoing research.

Euglycemic Diabetic Ketoacidosis With COVID-19 Infection in Patients With Type 2 Diabetes Taking SGLT2 Inhibitors.

OBJECTIVE: Diabetes mellitus is associated with poor outcomes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Diabetic ketoacidosis (DKA) has also been reported to occur with this virus. A cluster of cases of euglycemic DKA (euDKA) was identified in patients with type 2 diabetes mellitus using sodium-glucose cotransporter-2 inhibitors (SGLT2is) who developed SARS-CoV-2 infection. METHODS: The cases were identified by the authors while providing clinical care, and details were collected. RESULTS: Five cases of euDKA, presenting with glucose levels <300 mg/dL, were identified over the course of 2 months by the endocrinology consult service. All patients had a history of type 2 diabetes mellitus with no known history of DKA. All were taking SGLT2is. Oral antihyperglycemic medications were stopped for all patients on admission. All received intravenous insulin infusion to treat DKA before being transitioned to a subcutaneous insulin regimen. SGLT2i use was discontinued for all patients who were discharged. CONCLUSION: EuDKA has been seen in the setting of acute illness in patients using SGLT2is, but this cluster of cases suggests that there is a specific association with SARS-CoV-2 infection. In addition to the known risk of euDKA with SGLT2i use, coronavirus disease 2019-specific mechanisms may include a direct toxic effect of the virus on the pancreatic islets, an accelerated inflammatory response promoting ketosis, and the diuretic effect of SGLT2i in conjunction with anorexia and vomiting. It is crucial to counsel patients to stop SGLT2is when sick, especially if SARS-CoV-2 infection is suspected.
